CTL induction in mice by LFn-p24 with Alum in the presence and absence of PA. Chromium release CTL was conducted 1 wk after a single i.p. immunization with 15 μg of LFn-p24 plus 5 μg of PA (animals A–D), 15 μg of LFn-p24 plus 5 μg of PA formulated with 150 μg of Alum (animals E–H), and 15 μg of LFn-p24 with 150 μg of Alum, respectively. The diamonds represent lysis of target cells pulsed with the p20 peptide (antigen-specific cell killing), whereas the squares represent lysis of target cells that were not sensitized by the peptide (nonspecific cell lysis).
